GUID (UUID V4):

Comprised of six distinct ore bodies which have been identified by drilling efforts. The deposits yields a total reserve of 9.5 t Au with an average grade of 6 g/t.

In recent years, the Kunlun River goldfield (KLRA) in the SKL has gradually become an important gold mineralization belt because more than 10 gold deposits or occurrences were discovered throughout this area, among which the Heihaibei gold deposit is the largest.
Weak hydrothermal alterations within monzogranite wall rocks are mostly silicification and sericitization, with minor chloritization and carbonatization. In monzogranites, biotite is basically altered into chlorite, plagioclase is partially altered into muscovite, and hydrothermal quartz and/or calcite fill into fine fractures. More than 20 gold ore bodies (with Au abundances larger than the cut-off grade) and 30 auriferous bodies (with Au abundances below the cut-off grade) were delineated in the faulted monzogranite zone within the fault F53, and they yielded a total reserve of 5.7 t Au, with an average grade of 4.8 g/t, in which the 660 m long and average 5 m wide ore body M3 contributes to ca. 90% of the Au reserves. Most of the gold ore bodies strike EW to ENE (east-northeast) and occur as lenses along the faulted monzogranite zone within Fault F53. Ore bodies consist of predominant smoky grey quartz veins with minor stockwork quartz veinlets or breccias in the altered monzogranite, and smoky grey quartz veins are usually bordered by fault breccia belts in the faulted monzogranite belt.

The hydrothermal activity can be subdivided into three main stages. Stage I mineralization is formed as disseminated pyrite–arsenopyrite association which distributed in mineralized altered monzogranite. Stage II mineralization is characterized by mineralized smoky quartz–sulfide veins in the fractures of altered monzogranite, which are found as disseminated sulfide grains (pyrite and chalcopyrite), pyrite veinlet assemblage, and visible gold minerals. Stage III occurs as quartz and carbonate association which interspersed in the fractures of altered monzogranite, representing the post-ore stage.
